Start

‡Proposal1/ to introduce gas discharge light

sources with an objective luminous flux of

2000 lm

‡Proposal2/ to require automatic levelling for

all low beam headlamps independent from

±the light source technology

±the light source luminous flux

Automatic leveling proposal

‡Long transitional period of 90 months

‡GRE indicated

±to be open for relaxation of this new requirement

±for adopting alternatives based upon study

±in the beginning of this transitional period

‡Proposal2/ stalled in the GRE agenda and discussion was deferred for ~2 or 3 years

±until today

‡The expert from Poland worked on new initial aiming requirements

±Different approach

±OICA commented on this proposal

This is why Poland and OICA contribute with presentations to provide background information

‡Publically accessible home page

‡Concentrated on levelling in relation to load

‡Major objectives

±to improve the understanding of different factors that influence visibility and glare; start of the presentations ±to identify results of the study that might reveal alternatives for automatic static levelling; end of the presentations

±Field test by WG FL1/

‡Cooperation with DEKRA and TUD

‡Discussion in response to comments/ questions

±From GRE68

±From GTB in several sessions

±By simulations based upon assumptions

Assumptions

‡Every testing and simulation is based upon

certain assumptions and choice of parameters

±Each set of assumptions has its weaknesses

±GTB used an international accepted standard

CIE S 021/E:2011: Vehicle Headlighting Systems Photometric

Performance - Method of Assessment

±The expert from Poland

‡will explain their set of assumptions

‡agreement with GTB to disagree on some aspects

‡Alternatives for automatic static levelling

±Based upon the outcome of the studies

‡Headlamp aiming is always a compromise

±There is no perfect solution possible

±Glare complaints are inherent to visibility of the road ahead for the driver
